ABSTRACT:
An electrostatic inkjet apparatus includes a plurality of ejection electrodes and a plurality of control electrodes. The ejection electrodes are arranged in an ink chamber for containing ink including particulate matter with protruding from a front end of the ink chamber. The control electrodes are arranged in the ink chamber such that each of the ejection electrodes is placed between two adjacent control electrodes. A voltage controller applies a control voltage to two control electrodes adjacent to a selected ejection electrode which is in a floating state and thereby a potential of the selected ejection electrode is changed to an ejection level.
